Former state Representative George Eichhorn, who served three terms in the Iowa House before losing his seat in the 2006 election, announced that he will seek the Republican nomination for U.S. Senate this year.

Up to now, Tom Harkin’s only declared opponent was Cedar Rapids businessman Steve Rathje, who had less than $60 in campaign cash at the end of 2007. Harkin started the year with close to $3.5 million cash on hand.
